About the Phase4 PCB

Phase4 is an open source STM32 PCB design by Immanueldavidckp, published on GitHub. It is a board, with 32 components from 19 distinct parts.

Its main chip is the STM32G473RET6, from the STM32 family. By type, the board carries 16 capacitors, 5 resistors, 4 test points, 2 crystals, 2 LEDs and 1 IC.

It belongs with the rf & radio designs in this gallery.

From the project

KiCad 10 schematics for the Telematics Control Unit (Rev B), generated from the master design file. Each of the 7 sessions/zones is its own sheet; connectivity between zones is carried by global power symbols (+5V, +3V3, +3V8, VBATRAW, VBATPROT, 1V8MODEM, GND) and global labels**

No KiCad install is needed to generate or check. Open the .kicadsch files in KiCad 10** to run real ERC, assign footprints, and lay out the PCB (Part 5 of the design file).

Phase4: common questions

What microcontroller does the Phase4 use?

The Phase4 is built around the STM32G473RET6, from the STM32 family.

How many components are on the Phase4?

32 components, from 19 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Phase4 design files?

From the Immanueldavidckp/Phase4 repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Phase4 design in my own project?

The repository has no license, so all rights stay with Immanueldavidckp. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Phase4 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
